Transportation in Korea

First, Incheon airport-Seoul/Gyungki.

I personally prefer rent a car in abroad. You can also rent a Korean car if you have international license. Websites such as Skyscanner or expedia are now offer search engine for rent a car.

Train. Express train from terminal (T1) or T2 to the Seoul station. official site of express train is here. The best way to the every spots in Seoul.

Bus. It you have to go to the suburb like Gyungki. Bus may better but the reservation is a little bit tricky. However, please don’t be afraid because it serves English language. Official site is here. You can buy the tickets in the ticket office but it usually has a long line. You can not buy tickets inside the bus so the best way is make a reservation in advance.

Example. The bus site. From Incheon T 1 to Pangyo

Taxi. If you are together, may be it’s cost effective but they usually carry luggage up to 2 or 3. To the central Seoul, it costs about 50.000W without traffic. Buses are even more comforter when the traffic is heavy. Sadly, Uber is unavailable in Korea.

2. Second, Airport-local provinces

It depends where it is. Cities usually have a KTX train station. Basically, from Seoul station you can go every where if it is a city. (also Wonju)

If your destination is not a city, buses are the best way to go.

3. Buses and subway

Generally, Korean transportation ticket service offered by T-money. You can buy Tour card by T-money every convenient stores named CU, GS 25, seven eleven. I recommend you drop by seven eleven in the airport (1st floor) and buy below transport card (design sometimes can be changed). Can charge with cash only.
